A very import thing to check on the knives is whether they are the same height on each end. Mine shipped to me with one end high and the other low. the next knife was set the opposite. It could ruin a board in a heart beat. That was 30+ years ago and silly me, in my youth I thought tools came ready to use. I learned how to make the adjustments and have enjoyed it ever since. The next point of frustration was not setting the screw tight enough to stop the machine from self adjusting the depth of cut. More reading to catch up on then you make another adjustment.
